Tieguanyin: It is the best oolong tea produced in Yaoyang Township, Anxi County, Fujian Province. Picking technology: Picking four times a year, there is spring tea in the long summer, summer tea after the summer solstice, summer tea after the great summer heat, autumn tea thousands of years ago, and spring tea is the best. The finished tea is curly, plump, round, thick and even; Bright color, mellow and sweet taste, known as the king of tea. Drinking it has the effects of clearing away heart fire, improving eyesight, preventing arteriosclerosis, reducing blood fat and losing weight. Frozen-top Oolong Tea: Produced in the area of Frozen-top Mountain, a branch of Phoenix Mountain in Nantou County, Taiwan Province Province, the finished product is hemispherical, with dark green color, natural fragrance, orange soup color, mellow and moist taste, and the quality is the highest in spring tea. First, Tieguanyin to lose weight: use Tieguanyin to lose weight, and have a drink before and after three meals. It is best to drink hot tea without sugar. And don't drink it immediately after meals. It is more appropriate to drink it every 1 hour. Drinking tea should also adapt to personal physique. If you feel uncomfortable after drinking tea, such as stomachache or insomnia, you'd better stop. When making tea, the water temperature should be controlled at about 80℃-90℃; The brewed tea should be drunk within 30-60 minutes, otherwise the nutrients in the tea will be oxidized. Second, the beauty of Tieguanyin can reduce serum neutral fat and cholesterol; The clinical experiment of delaying aging also suggests that Tieguanyin can improve SOD activity. It can be inferred that Tieguanyin is likely to have a certain health care effect on the skin. As an indicator of healthy skin, it can be listed as follows, such as moist skin, elasticity, tension, good blood circulation and so on. What effects will fat metabolism and active oxygen scavenging have on skin health? We further did the following experiments. In order to find out whether drinking Tieguanyin is related to skin beauty, we selected 73 healthy China women aged 2 1 ~ 55 as the research objects for clinical experiments. Let everyone drink 4g Tieguanyin every day, 2g in the morning and 2g in the afternoon for 8 weeks. Then observe the changes of sebum content and water retention capacity, and take the change as an index to measure the drinking effect. 1. Detection of neutral fat content in sebum After washing your face with soap, make-up and touch are not allowed on the tested parts, and eating is forbidden after breakfast. Wash your face for 4 hours before taking samples. The detection method is to stick a 2×2cm degreased filter paper on the forehead of the detected object, apply a pressure of 100g, and then take samples. Then measure the neutral fat, the main component of sebum membrane, and compare the changes before and after drinking Tieguanyin. 2 Changes in the amount of neutral fat in the sebum membrane The average amount of neutral fat in the sebum membrane before and after drinking Tieguanyin was 33.7μg/cm2, which was significantly reduced after the experiment. In order to further understand the efficacy of Tieguanyin, we divided the subjects into two groups according to the amount of sebum before the experiment, namely the above-average group and the below-average group. Results: Before and after the experiment, the group with low sebum content was 65,438+07.2 μ g/cm2 and 65,438+08.5 μ g/cm2, respectively, with no significant difference, while the group with high sebum content was 54.9 μ g before the experiment. This analysis shows that Tieguanyin does not simply reduce the sebum content after drinking, but has a greater effect on people with high sebum content than those with low sebum content, indicating that Tieguanyin has the function of regulating the balance of sebum content. 3. The skin water retention experiment further determined the skin water retention. Because the moisture content of skin is easily influenced by the external environment, the experiment adopts a room with a certain temperature and humidity, and measures it after entering the room for 30 minutes. The part to be measured is the cheek. First, measure the skin moisture in the natural state, then drop distilled water on the same part and wipe it before measuring. After that, it should be measured every 30 seconds and recorded. After dripping distilled water on the skin, the stratum corneum absorbs water temporarily, and then gradually dries with time, and the water decreases. Through its detection, we can know the water retention ability of skin. Water retention capacity is often expressed as "water retention rate". Water retention rate refers to the ratio of water content after skin dripping 120s to water content in natural state (water retention rate (%) = water content after dripping 120s/water content in natural state × 100). The greater the water retention rate, the higher the ability to "seal" water in the stratum corneum. The water retention rates before and after this experiment were 122% and 137% respectively, and the water retention rate of skin increased after the experiment. In addition, similar to the analysis of the results of the above sebum grouping experiment, we also divided the people whose water retention rate was lower than the average and higher than the average before the experiment into two groups for analysis and comparison. Results: The water retention rate of the group below the average level was 94% before the experiment and increased to 129% after the experiment, which indicated that drinking Tieguanyin significantly improved the water retention capacity of the stratum corneum. The above experimental results show that drinking Tieguanyin for a long time can promote sebum balance and improve the water retention capacity of stratum corneum. Third, activate autonomic nervous system to relieve stress. Tieguanyin can improve the activity of autonomic nerve and parasympathetic nerve, prevent overeating caused by excessive pressure, and eat hard because of anxiety, which helps to lose weight. Fourth, improve energy metabolism. Japan tested water, green tea and Tieguanyin to improve the basic metabolic function. The results show that water has no special effect. Green tea can improve the metabolism of 4 calories 1 hour, and Tieguanyin can improve the metabolism of 9 calories the most! As we all know, drinking tea has many benefits. But why does drinking tea have many benefits? For the average person, this is knowing it but not knowing why. Tieguanyin is not only fragrant and mellow, but also a natural and delicious drink, and its health care function is also outstanding in tea. Modern medical research shows that Tieguanyin not only has the health care function of ordinary tea, but also has the functions of anti-aging, anti-cancer, anti-arteriosclerosis, anti-iss disease, weight loss and bodybuilding, prevention and treatment of dental caries, clearing away heat and reducing fire, and relieving hangover and other effects. Nutritionist Yu Ruomu said: "Tea contains many beneficial ingredients, which can regulate human metabolism. The mechanism of tea anti-cancer, anti-aging and improving human physiological activity has also been basically studied. Therefore, tea is the best drink that nature has given to mankind. " Mr. Lu Xun once said: "It is a blessing to have good tea and drink good tea." By the beginning of the19th century, through modern scientific separation and identification, tea contains more than 450 organic chemical components and more than 40 inorganic mineral elements. Organic chemical components and inorganic mineral elements in tea contain many nutrients and medicinal components. Organic chemical components mainly include tea polyphenols, plant alkaloids, protein, amino acids, vitamins, pectin, organic acids, lipopolysaccharides, sugars, enzymes and pigments. Tieguanyin contains organic chemical components such as tea polyphenols, catechins and various amino acids, which are significantly higher than other teas. Inorganic mineral elements mainly include: potassium, calcium, magnesium, cobalt, iron, manganese, aluminum, sodium, zinc, copper, nitrogen, phosphorus, fluorine, iodine and selenium. Tieguanyin contains more inorganic mineral elements such as manganese, iron, fluorine, potassium and sodium than other teas.
